Abstract
An engine mounting structure characterized in that a shock and vibration insulating unit and a vibration cancelling device are provided operatively in parallel with each other between the body structure of an automotive vehicle and the engine mounted on the vehicle body structure, wherein the vibration cancelling device comprises at least one rigid elongated bar having one end portion pivotally engaged by the body structure of the engine and a longitudinally intermediate portion pivotally engaged by the vehicle body structure, and a mass or counterweight member carried by another end portion of the elongated bar whereby the vibrations to be transferred through the shock and vibration insulating unit are at least partially cancelled by the vibrations to be transferred through the vibration cancelling device.
Claims8
An engine mounting structure for mounting an automotive engine on the body structure of an automotive vehicle, comprising:
- a first bracket member to be connected to the body structure of the engine,
- a second bracket member to be connected to the body structure of the vehicle and spaced apart from the first bracket member,
- a shock and vibration insulating unit structurally intervening between the first and second bracket members and including at least one resilient block, and
- a vibration cancelling device comprising rigid first and second elongated members, the first elongated member having one end portion pivotally connected to said first bracket member and the second elongated member having an end portion pivotally connected to said second bracket member, said first elongated member having a longitudinally intermediate portion pivotally connected to the second elongated member, and a mass member connected to another end portion of said first elongated member.
